Google just released an easy way to embed waves on your web site. The Google Wave web element puts a wave on any web page--with anonymous access. That means even people not signed into Wave can read and watch waves that you've made public and embedded. (Wavers, here's how to make a wave public.) Anonymous users can watch a wave change over time on your site, but they won't be able to edit it.
Let's give it a try. After the jump, check out my first embedded public wave with anonymous, non-signed in access.
You can also edit the width and height variables to fit the embedded wave to your site's dimensions if the web element's presets don't work for you. I changed mine, above, to 700x2000 pixels.
You can also give a Google group of users access to a particular wave, which comes in very handy if you want to embed a wave but be selective about who has edit rights. If your Google group's settings are "Anybody can view group content", then only group members could edit the embedded wave, but everyone else could see updates.
If web site publishers hop onto this bandwagon, anonymous and embedded wave access could go a long way to boosting Wave adoption and usage. Can't say I wouldn't be thrilled to see that happen.
